Apache ZooKeeper 3.5.3-beta Has Been Released

The Apache ZooKeeper team has announced that Apache ZooKeeper release 3.5.3-beta is now available! This release is the first beta release of the 3.5 series, which cover 77 issues, thirteen of which were considered blockers. Here are some highlights:

New Feature

ZOOKEEPER-2719 Enable creation of TTL nodes, which are znode that’s not tied to a session and will get cleaned up automatically once expired.

Security Fixes

ZOOKEEPER-2014 Only admin roles should be allowed to reconfigure a cluster

The 3.5 series has been through three alpha releases already, incorporating feedback from users and addressing found issues. The Apache community is now considering the 3.5.3 release to be of beta quality. It is important to note that 3.5.3 is not yet ready for production. It is an early release that users can start testing so that we can stabilize later 3.5.x release towards the stable 3.5 release, which we will adopt into a future CDH release.
